[G4] PCI and AGP expansion slots.

[Rick Smykla]

Patrick,

For what it's worth, every PCI USB 1.1 adapter card that I've tried  
(in every G4 I've tried them in), have worked without regard to  
manufacturer. USB 2 cards that are compatible with OS X are more of a  
mixed bag; many are recognized, but may only operate at slower  
speeds. Check for OS compatibility before shelling out your money.

As to graphics cards, those absolutely must have compatible driver  
software to work in a Mac. Some older PCI cards can be ROM-flashed  
for OS X-compatibility, but preferably you'll want an AGP card  
specifically designed for the Mac, e.g., one of ATI's "Mac Edition"  
cards.  <http://www.xlr8yourmac.com/> is a good place to look for  
reports on specific graphic card/machine configuations.

HTH,
Rick
